Health Hazard Evaluations (HHEs)

Each month we will update this page to highlight newly released final reports and information on new and emerging hazards we are evaluating. Check back often to see what we are up to!

What's New

Evaluation of Heat Sealing Operations at a Plastic Film Assembly Facility
Health Hazard Program investigators found possible work-related asthma and low levels of various aldehydes in air samples. Employee symptoms improved after a change in source materials, but some continued to experience headaches and asthma-like symptoms. Finding carbon monoxide in areas with and without forklift use, we recommended properly maintaining forklifts, and conducting full-shift carbon monoxide exposure monitoring.

Finding overexposures to hexavalent chromium and cadmium in the air and nasal tissue damage consistent with chromium exposure, HHE Program investigators recommended medically monitoring employees, improving ventilation in stripping and painting bays, and requiring the use of airline respirators for employees who apply primer or paint, or who do sanding.
